5 Claims.

The present invention relates to washing devices and has main application in washing glasses, cups, pots, and other like containers.

'.Ihe principal object of the present invention is the provision of a washing device having a central brush over which the container is positioned and into which the brush is receivable, with a plurality of other brushes adapted to contact the container outwardly, and so arranged that when manual pressure is exerted on the container, all brushes may bodily turn with respect to a container manually held against rotation, with means for reversing the movement of the brushes in the opposite direction.

A still further object of the present invention is the provision of a washing device of the character indicated and wherein a carriage may be provided for supporting a plurality of brushes, and which carriage, under the pressure exerted upon the container may be shifted downwardly and against the pressure of tensioning means, with suitable guides provided guiding said carriage in its rotary movement to impart rotation to the brushes so that the same may shift with respect to the container and held against rotation with respect to the brushes for the purpose o f cleaning the container. A still further object of the present invention is to generally improve the construction of a washing device of the character hereinabove indicated.

' With the above general objects in View and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views:

Fig. 1 is a side elevational view of the present device;

Fig. 2. is an enlarged cross-sectional View on a vertical plane, on line 2 2 of Fig. 1, showing the washing device in an inoperative position;

Fig. 3 is a top plan elevational view of the present device, the brushes thereof being shown in a cross-section;

Fig. 4 is a vertical cross-sectional View of the lower portion of the device when the same is in ,all Peaftive FQStiQl; and

view of a brush carriage, with brushes removed therefrom.

Referring in detail to the present drawings there is shown therein a cylindrical casing I0 open at both ends thereof. Positioned within the lower end of said casing I0 is a radial threearmed frame II, each arm thereof being provided with an upwardly extending lug I2 whereby the frame may be rigidly affixed to the casing II'I by means of rivets I3. Each of saidarms of frame II carries a laterally extending arm I4 to each of which in turn a suction'cup I5 is a'ixed. Said casing I0 is adapted to be receivable within container I6 lled with water, and said suction cups I5 are adapted to engage the bottom of said container I5 by means of suction so as to prevent casing I0 from lateral or upright movement when in said containerl I6.

Integrally formed with said arms of frame II and centrally thereof is bushing I'I. A conical coil spring I8 is afxed by its lower end to the arms of frame II as at I9, it being noted'that the base of said coil spring I8 is considerably wider than its upper end, so that when said spring I 8 is depressed, as illustrated in Fig. 4, the strands thereof assume a horizontally co-planar position;

The device further includes a three-armed frame or carriage 20 which centrally thereof is provided with a suitable aperture for insertion of tube 2|, the lower end of which is frictionally held within central aperture made in the said carriage- 20, yforv the purpose of receiving the upper end of tubular shaft 22, the lowerend -of which is frictionally held within a central bore provided in bushing I'I.

" Rigidly aiiixed to casing I0 and on the inner periphery thereof are three pairs vof rails 23, each pair 'of which is rigidly connected by a crosspiece 24, at the upper end of each pair of s'aid rails 23.v Each pair of said rails 23 denne a helical channel p25.'

The outer end of each arm of said three-armed carriage 20 is provided with an integrally formed and downwardly depending lug 26 apertured at its center to receive r'screw 2l having an enlarged smooth shank 2 8 and screw headv 29. Nut 30 prevents creeping movement of said screw 21 with respect to said lug 25. Receivable upon shank 2 8 and adapted for free rotation thereon is anti-friction roller 3l. The adjacent face of said lug 2liy as well as head k29 prevent lateral movement ,of said roller 3|. Casing I0 and adjacent its upper end is provided with three openings 32 at points which are coincidental with the posi# Fig. 5 is a fragmentary top plan elevational 55 tion of 'said screw 2l whenv carriage 20 remains in an inoperative position illustrated in Figs. l and 2, so that a screwdriver may be inserted through said opening 32 either for removing said screw 21 or for affixing the same to lug 26.

Central brush, insertable within a cup preparatory for washing the same, includes horizontal strands 33 and upwardly projecting strands 34, the latter at the upper end of said brush. Horizontal strands 33 are cylindrically arranged, as is clearly seen in Figs. l and 2. All of said strands are mounted upon a tubular shaft 35 provided with a central bore 36, the lower end of which is lined by a metallic tube 31 frictionally held within said shaft 35. The outer lower end of said shaftl 35 is lined by a tubular guard 38 which is held in position upon said shaft 35 by a plurality of crimps 39. Adjacent the upper end of bore 35 said shaft 35 is further provided with a plu rality of lateral openings 40 for the purpose here-- inafter stated.

Rigidly aiiixed to the central portion of carriage 2G by its ange 4| is socket 42 which remains in a concentric relation with tube 2| and shaft 22 as is seen in Fig. 5. Made in guard 38 and in the adjacent body portion of shaft 35 is a bore 43 for the purpose of receiving therewithin a catch lug 44 the latter carried by a tensioned plate 45, the lower end of which is affixed to one of the arms of carriage 20 as at 45. Socket 42 coincidental with catch lug 44 is provided with a laterally extending spacing lug 41 through which said catch lug 44 is adapted to pass as is seen in Fig. 2. Integrally formed with said spacing lug 41 is a rectangular guard plate 48 within which plate 45 is adapted to shift.

From the hereinabove construction of brush 33-34 and its mounting means upon carriage 23, it will be apparent that the lower end of shaft 35 with its tubular guard 38 is insertable within socket 42, on first manually deflecting plate 45 away from said socket 42 for the purpose of retracting catch lug 44 from within said socket 42. When the lower end of said shaft 35 is in position within said socket 42 and bore 43 is in an alignment with said catch lug 44, the manual hold on plate 45 is released for permitting said lug 44 to spring into bore 43. This arrangement will permit said brush 33-34 with its shaft 35 to remain in a rigid stationary position with respect to carriage 20. Tube 2| forms a guide for shaft 22 and permits a free sliding movement of the latter within said tube 2|, as will hereinafter be apparent.

Co-operating with said central brush 33-34 are three outer brushes each mounted adjacent the end of each arm of carriage 20, as is clearly seen in Fig. 3,' and each of said outer brushes includes shaft U provided with horizontally extending bristles 5| disposed towards and normally contacting with horizontal bristles 33 of the central brush. Each of said shafts and at the lower end thereof is provided with an annular, crimped guard 52, receivable within socket 53, the latter integrally formed with each arm of carriage 2|).

To rigidly affix said shafts 50 to the respective arms of carriage tensioning plate 54 is provided, the same being afxed by its lower, horizontal leg portion to the arm as at 55. Each of said plates 54 carries a catch lug 56, extending through an opening made in the adjacent periphery of socket 53 and a coincidental bore 51 made in the lower end of shaft 50. Rigidly formed with socket 53 is a rectangular guard plate 58 within which the upright portion of plate 54 is positioned and within which the same is adapted for shifting movement for the purpose of manually retracting said plate 54 away from socket 53 with its lug 56 from its engagement with shaft 50. When said shafts 5|) are in an operative position on carriage 20 they will be in a rigid engagement therewith through the medium of said catch lug 56.

Assuming that the device is within a receptacle 6, the latter filled with water, with suction cups l5 engaging the bottom of said receptacle I6, with brushes and carriage 20 in an inoperative position shown in Figs. 1 and 2, a container such as glass while in an inverted position is pressed over the central brush 33--34 and is shifted downwardly so that the bristles thereof completely fill the container and contact with its inner peripheral wall and bottom. The ends of the outer brushes by their bristles 5| will at the same time contact with the outer periphery of the container. While a container remains in that position with respect to the two sets of brushes a manual hold is maintained adjacent the bottom end thereof, and simultaneously the container is pressed downwardly for the purpose of shifting carriage 20 downwardly and imparting thereto a rotary movement through the medium of rollers 3| as they press lower rails 23 and ride upon the adjacent faces thereof.

Since channels 25 are of a helical or spiral formation a simultaneous downward and rotary shifting movement to carriage 2B will be imparted and likewise to said brushes 33--34 and 5|. Said carriage 25J will shift in the manner indicated and against the pressure of spring i3, until saidcarriage and brushes will assume the position illustrated in Fig. 4. It is observed that the upper end of spring I8 merely contacts with the underface of carriage 29, but is not attached thereto in any manner, permitting a free sliding movement of said carriage upon the upper end of spring I8. When the downward maximum shifting movement of carriage 20 is attained, spring I8 will fold until the same reaches the position illustrated in Fig. 4.

When the downward pressure at the container, as the same remains in position upon brush 33 34, is released, carriage 25 with the brushes will rise upwardly due to the upward tension of spriing |8 and will make a reverse rotary motion due to the arms of said carriage 2G being guided by rollers 3| within their respective channels 25 made by rails 23. In the reverse upward and rotary movement of carriage 2|) and of the brushes, rollers 3| will contact the adjacent faces of upper rails 23.

During operation of the device casing IB, and if preferred brushes 33--34 and 5|, or major portions thereof, are immersed in water within container l5 as is indicated in Fig. l. To eliminate compression or suction of water within bore 33 in shaft 35, which otherwise would ensue on downward or upward movement of said. shaft 35, openings 40 in the upper end ofshaft 35 are provided, to communicate with said bore 35, through which the air in bore 36 may be ecpellcd on downward movement of shaft 35, and through which air may enter said bore 35 on upward movement of said shaft 35. By virtue of this arrangement the pressure upon water which may remain within said bore 3B and shaft 22 will be unaffected by virtue of the upright sliding movement of said shaft 35. Y

One of the advantages of the device herein dis closed resides in the fact that the load and weight of carriage 20 as the same makes simultaneous entirely upon spring I8 and shaft 22 but is distributed laterally to the several pairs of rails 23, where part of the load is taken up by rollers 3l as they make sliding movement within their respective channels 25 and as they contact with their respective pairs of rails 23.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
